SAFETY RAZOR.

Application filed January 22, 1921. Serial No. 439,148.

To all 10.7mm it may concern:

Be it known that I, WALTER Nowan, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.

My present invention relates 'enerally to safety razors and more particularly to that t 'pe of safety razor employing double edged blades clamped upon the outer convex face of a guard plate and between this guard plate and a clamping plate, my object being the provision of certain novel connections whereby the clamping plate may be secured in connection with the guard plate in such manner as to permit of its ready association therewith and disassociation therefrom.

In the accompanying drawing which illustrates my present invention and forms a part of this specification,

Figure 1 is a perspective view of my impr ved safety razor complete,

Figure 2 is a sectional view thereof, the section being taken lengthwise through the head,

Figure 3 is a detail perspective view of the clamping plate removed,

Figure 1 is a similar view of the guard plate with its handle, and

Figure 5 is another similar view of one of the blades.

Referring now to these figures my invcn tion proposes a safety razor-inchuling a handle in rigid connection with one end of which is a guard plate 11 having an outer convex face turned away from the handle, this guard plate being provided with apertures 12 adjacentto its opposite ends in line with its longitudinalaxis, and also in line with end lugs 13. which latter are curved and deflected rearwardly toward and upon opposite sides of the handle 10 and are provided with terminal engaging edges 11 for a purpose which will be presently described.

The guard plate is alsoprovided along its longitudinal side edges with the usual guard fingers 1-5 adapting the same for co operation with the cutting edges 16 of a blade 17 such shown in Figure 5, whose ends have central recesses 18 to register with the openings 12 of the guard plate when the double edged blade is disposed upon the outer convex surface of the guard plate.

The clamping plate 19 shown particularly in Figure 3 is also curved in cross section and its function is to clamp the blade 17 firmly; and uniformly upon the outer surface of the guard plate 11, the blade flexing for this purpose as is usual, and this clamping plate in accordance with'my invention has integrally struck up and rearwardly projecting tongues 20 at its opposite ends, whose'laterally and outwardly oifsetextremities 21 have bosses 22 adjacent to the shoulder or offset, adapted for engagementby the inner engaging edges 14 of the guard plate lugs 13.

To the above end, association of parts in operative relation involves the disposition of the blade 17 upon the outer face of the guard plate 11 so that its end recesses 18 register with the guard plate openings 12. The tongues 20 of the clamping plate 19 the are then pressed slightly toward one another against their natural spring tension in order that their free offset ends 21 can be shifted rearwardly through the recesses 18 of the blade and the openings 12 of the guard plate so that when the clamping plate 19 is pressed firmly against the blade and the latter thus firmly and uniformly clamped against the outer surface or blade seat of the guard plate to the position shown in Figures 1 and 2, the inner offset ends of the tongues will spring outwardly at the rear of the lugs 13 of the guard plate and the free 'engag ing edges 1a of the latter will engage the bosses 22' and thus effectively clasp the clamping plate in effective position.

This effective position will be retained until the operat-orgrasps the rear free ends of the tongues 20 and presses the same toward one another against their natu 'al spring tension and free of the engaging edges 1a of lugs 13 upon which the natural tension of the normally fiat blade 17 willspring the clamping plate 19 forwardly away from the guard plate in order that it may be grasped and pulled. entirely free for ready removal of the blade.

My invention thus presents an arrangement by means of which the blade may be readily clamped and immovably held, without the use of additional positioning pins and apertures, and by the simple provision of end recesses in the blade which leave the latter particularly strong and durable, impairing as they do to a minimum extent the natural strength of the metal. clamping means proposed by my invention permit of ready association and disassocia- The tion of the parts, plesent a neat compact appearance without interfering in any way with proper manipulation of the razor in use, and coact in the formation of a strong and durable structure which avoids threadguard plate and provided with means movable into clasping engagement with the rear eifective ends of the'lugs of the guard plate as described.

2; In a safety razor, a guard plate and blade thereon having registering cutout portions, said guard plate having rearwardly projecting and inwardly inclined end lugs Whose rear effective-ends are alined with and spaced rearwardly from the guardplate cutout portions and a clamping plate for holding the blade in place, having projecting resilient tongues insertable through the cutout portions and shiftable into c-lasping relation with the rear effective ends of said lugs as described.
